Learning Objectives (Aligned with Common Core and NGSS)

• I can define what a cell is and explain why it is called the basic unit of life.
• I can describe the structure and function of key cell components.
• I can differentiate between prokaryotic and eukaryotic cells.
• I can identify and explain the roles different cells play in living organisms.

Standards Alignment:

Common Core State Standards (CCSS) Integration:

• CCSS.ELA-LITERACY.RST.11-12.1: Cite specific textual evidence to support analysis of science texts.
• CCSS.ELA-LITERACY.RST.11-12.4: Determine the meaning of symbols, key terms, and other domain-specific words.
• CCSS.ELA-LITERACY.WHST.11-12.2: Write informative/explanatory texts to examine scientific concepts clearly.

Next Generation Science Standards (NGSS):

• HS-LS1-1: Construct an explanation based on evidence for how the structure of cells relates to their function.
• HS-LS1-2: Develop and use models to illustrate the functions of a cell and its components.

Materials Needed

• Projector and computer for presentation
• Interactive digital cell model (accessible online or software installed)
• Printed dyslexia-friendly handouts on cell basics with visuals
• Whiteboards and markers (classroom sets)
• Cell structure flashcards (color-coded)
• Graphic organizers for note-taking
• Microscopes and prepared slides (if available for extension/demo)

Detailed Lesson Breakdown

1. Engagement / Hook (5 minutes)

• Begin with a provocative question on the board:
  “If cells are so tiny, how can they make up an entire living being — you?”
• Brief class discussion (whole group, low-pressure, 1-2 students share)
• Show a captivating time-lapse video of cell division (1 minute) to inspire curiosity.

---

2. Direct Instruction (12 minutes)

• Use a multimedia presentation to cover:
  • Definition of a cell & why called the basic unit of life
  • Overview of cell structure (nucleus, cytoplasm, membrane) focusing on visuals and simple analogies (e.g., nucleus = “control center”)
  • Differentiate Prokaryotic cells (simple, no nucleus) vs. Eukaryotic cells (complex, with nucleus)
  • Examples of cell types and their functions in organisms
• Incorporate pause points for quick “thumbs up/down” comprehension checks.
• Use key vocabulary highlighted in bold on slides and provide dyslexia-friendly handout matching content.

3. Guided Practice / Interaction (15 minutes)

Activity 1: Digital Cell Exploration (10 minutes)

• Students break into small groups (4-5 students each; Honors students lead groups)
• Each group explores an interactive cell model on tablets/laptops (or via classroom computer stations)
• Task: Identify cell parts, note their functions, and classify cells as prokaryotic or eukaryotic using a graphic organizer provided
• Teachers or aides circulate to support students with accommodations (e.g., clarifying questions, reading assistance)

Activity 2: Quick Write & Pair-Share (5 minutes)

• Students write a brief response: “Why are cells important to life?”
• Pair-share with neighbor to rehearse their explanation aloud.

---

4. Independent Application (10 minutes)

Cell Structure Flashcard Quiz (Formative Check):

• Students receive a set of flashcards
• They match cell parts to functions and classify cell types in individual whiteboards
• Submit whiteboards for teacher quick assessment
• Honors students challenged to write a 2-3 sentence summary connecting cell structure to function

---

5. Closure / Review (5 minutes)

Exit Ticket Prompt:

• On a sticky note or digital form, students write: *“One thing I learned today about cells is…” and “One question I still have.”
• Collect these for formative assessment and to inform the next lesson

---

Success Criteria

• Accurately define a cell and explain its role in living organisms.
• Identify and describe at least three key cell parts and their functions.
• Correctly distinguish between prokaryotic and eukaryotic cells.
• Demonstrate ability to use scientific vocabulary related to cells in explanations.

---

Differentiation Strategies

Learner Type	Strategy
Honors Students	Leadership roles in groups, extended written synthesis task, research project teaser on organelles during free time.
Students with Accommodations	Use dyslexia-friendly printouts, extra time for activities, paired work for peer support, audio recordings of lesson key points available.
Regular Education Students	Mixed grouping to balance peer interactions; scaffolded graphic organizers.

Extension Activities for Advanced Learners

• Research and prepare a short presentation on specialized cells (e.g., neurons, muscle cells) for the class.
• Write a brief comparative essay on how cell structures differ between plants and animals.
• Begin a “Cell Journal” to note new vocabulary and discoveries during the unit.

---

Dyslexia-Friendly Reading Options

• Printouts use clear, sans-serif fonts such as OpenDyslexic or Arial, 14+ point size
• Use bullet points, short sentences, and vivid illustrations
• Highlight vocabulary words in color with simple definitions alongside illustrations
• Provide audio versions of handouts via school learning platform

---

Reflection / Notes for Next Lesson Preparation

• Monitor student exit tickets for common misconceptions or questions about cell types or structure.
• Prepare targeted mini-lessons or visuals to reinforce difficult concepts.
• Plan incorporation of microscope exploration early in the next lesson for tactile learning opportunities.
